RE: DMRGateway
This the setup I currently use for Legacy TGIF on Network 4 and Prime.TGIF on Network 5

After the switch is thrown to do the move from legacy to prime, I will simple switch the Address line in Network 5. This will allow me to connect to the new sever with an unsecured connection on network 4 and a secured connection on network 5
